Xen users - Aug 2005 - no BkSp in plan9, ubuntu root fs failure, and what''s up with bsd?

In usual fashion, I have a few questions:

1) I can''t get the virtual terminal of plan9 to recognize either my
Backspace or Delete key.  This is particularly annoying; can anyone help?

2) I''ve got two linux root fs images that I created through dd: one for
rubix and another for ubuntu.  Rubix works brilliantly, but Ubuntu gets
a kernel panic during boot.  The two both mount have the line

    disk = [ ''file:/path/to/image/os.img,/dev/sda1,w'' ]

and

    root="/dev/sda1 rw"

where "os" is either "rubix" or "ubuntu". 
Ubuntu''s failure reads

    Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(8,1)

I don''t understand why one should work and the other
shouldn''t; any ideas?

3) Where can I find a howto on setting up a guest BSD system?  So far
all I''ve found are places where people say that they''ve ported
BSD to
Xen, and how to make NetBSD a dom0, but nothing about how to set up an
xm config file or what you need in order to run BSD properly.  Can
someone point me in the right direction please?

Sorry to hit so many diverse areas, but these are the real headaches
I''m
dealing with.  I appreciate any help.

I''m running dom0 on Linux with NetBSD as one of the guest domains.

The config file is as follows:

------------------- cut here ----------------

# Kernel image file.
kernel = "/boot/XEN/netbsd-xenU"

vmid = 1

# Initial memory allocation (in megabytes) for the new domain.
memory = 64

# A name for your domain. All domains must have different names.
name = "NetBSD"


#----------------------------------------------------------------------------
# Define network interfaces.

# Number of network interfaces. Default is 1.
nics=1

vif = [ ''mac=00:00:00:01:42:67'' ]

#----------------------------------------------------------------------------
# Define the disk devices you want the domain to have access to, and
# what you want them accessible as.
# Each disk entry is of the form phy:UNAME,DEV,MODE
# where UNAME is the device, DEV is the device name the domain will see,
# and MODE is r for read-only, w for read-write.

disk = [
''phy:/dev/vgsystem/lvnetbsd,sda,w'',''phy:/dev/vgsystem/lvnetbsdswap,sdb,w''
]

------------------ cut here -----------------

This defines two SCSI ''disks'' for NetBSD which are backed by
LVM
volumes. To get the needed NetBSD kernel you just enter your Xen source
directory and do a "make netbsd20".

       Alex.
